This is a probiotic that packs a punch. The ingredients include live beneficial bacteria. My horse wa svery attracted to the pellet and seemed to enjoy the taste! At one point he tried to steal the whole tub! I will have to update on his poop once he has completed the whole 30 days. I am also hoping for some bloating release. So far I am very please with the palatable taste and pellet formula. It is so much better that powders!

Our Saving Grace

We use MQ for one of our show minis as she becomes a nervous wreck when traveling to and from shows. MQ has become a saving grace on limiting the grooming needs once reaching the show as the mini is white and used to get liquid poops while traveling. But that is no longer a problem since she’s been on MQ.

My 28 year old gelding occasionally gets fecal water syndrome, causing extra liquid with his formed manure. Within a few days, this product cleared it up, and his hind legs are clean once again. With CFU’s in the billions, and most other products only in the millions, it does the job. The pellets are palatable, and easy to mix in with the feed. Very happy!

This product is very respectable. Anytime my horse is on an antibiotic now I will be sure to pair it with this product. It is not just full of sugar like many of the horse probiotics on the market and there’s actual research to show that it can make it where it needs to go. I commend Purina on this one. It is also very palatable.
